Ophthalmology is a surgical subspecialty within medicine that deals with the diagnosis and treatment of eye disorders. A former term is oculism.
LASIK or Lasik, commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and an actual cure for astigmatism, since it is in the cornea. LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity.
Refractive surgery is optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea (keratomileusis), lens implantation or lens replacement. The most common methods today use excimer lasers to reshape the curvature of the cornea. Refractive eye surgeries are used to treat common vision disorders such as myopia, hyperopia, presbyopia and astigmatism.
Fuchs dystrophy, also referred to as Fuchs endothelial corneal dystrophy (FECD) and Fuchs endothelial dystrophy (FED), is a slowly progressing corneal dystrophy that usually affects both eyes and is slightly more common in women than in men. Although early signs of Fuchs dystrophy are sometimes seen in people in their 30s and 40s, the disease rarely affects vision until people reach their 50s and 60s.
José Ignacio Barraquer Moner was a Spanish ophthalmologist and inventor born in Barcelona who did most of his life's work in Bogotá, Colombia.
Pellucid marginal degeneration (PMD) is a degenerative corneal condition, often confused with keratoconus. It typically presents with painless vision loss affecting both eyes. Rarely, it may cause acute vision loss with severe pain due to perforation of the cornea. It is typically characterized by a clear, bilateral thinning (ectasia) in the inferior and peripheral region of the cornea, although some cases affect only one eye. The cause of the disease remains unclear.
Gholam A. Peyman is an Iranian American ophthalmologist, retina surgeon, and inventor. He is best known for his invention of LASIK eye surgery, a vision correction procedure designed to allow people to see clearly without glasses. He was awarded the first US patent for the procedure in 1989.
Sheraz Daya is a British ophthalmologist. Daya founded the Centre for Sight in 1996, and works in stem-cell research and sight recovery surgery.
Gerard Sutton is an Australian ophthalmic surgeon and ophthalmologist in Australia and New Zealand. His specialty is laser vision correction, cataract and lens surgery, and corneal transplantation.
Tilganga Institute of Ophthalmology, formerly called the Tilganga Eye Centre, in Nepal is the implementing body of the Nepal Eye Program, a non-profit, community based, non-government organization launched in 1992. It was founded in part by renowned ophthalmologist and cataract surgeon Sanduk Ruit. The current facility was opened in 1994. The World Health Organization recognized Tilganga Institute of Ophthalmology as a WHO Collaboration Centre of Ophthalmology in 2019. In Nepal, it is the second institute, and first institute in the field of ophthalmology to receive this designation. It provides various sub speciality services of Ophthalmology such as Cornea, Cataract & IOL, Glaucoma, Oculoplastic, Lacrimal and Ocular Oncology services, Pediatric Ophthalmology and Strabismus services, Vitreo-Retina, Uvea, Neuro ophthalmology and Optometry services.
The Himalayan Cataract Project (HCP) was created in 1994 by Dr. Geoffrey Tabin and Dr. Sanduk Ruit with a goal of establishing a sustainable eye care infrastructure in the Himalaya. HCP empowers local doctors to provide ophthalmic care through skills-transfer and education. From its beginning, HCP responds to a pressing need for eye care in the Himalayan region. With programs in Nepal, Ethiopia, Ghana, Bhutan and India they have been able to restore sight to over one million people since year since 1994.
Noshir Minoo Shroff is an Indian ophthalmologist, notable for intraocular lens implantation surgery in India and a medical director of the Shroff Eye Centre. The Government of India honoured him in 2010, with the Padma Bhushan, the third highest civilian award, for his services in the field of medicine.
Post-LASIK ectasia is a condition similar to keratoconus where the cornea starts to bulge forwards at a variable time after LASIK, PRK, or SMILE corneal laser eye surgery. However, the physiological processes of post-LASIK ectasia seem to be different from keratoconus. The visible changes in the basal epithelial cell and anterior and posterior keratocytes linked with keratoconus were not observed in post-LASIK ectasia.
Vijay Kumar Dada is an Indian ophthalmologist and a consultant at the Sir Ganga Ram Hospital, New Delhi. An alumnus and a former chief of the Dr. R. P. Centre for Ophthalmic Sciences of the All India Institute of Medical Sciences, he has written several articles on eye diseases such as cataract and glaucoma. Dada, an elected fellow of the National Academy of Medical Sciences, was honored by the Government of India, in 2002, with the fourth highest Indian civilian award of Padma Shri.
Corneal hydrops is an uncommon complication seen in people with advanced keratoconus or other corneal ectatic disorders, and is characterized by stromal edema due to leakage of aqueous humor through a tear in Descemet's membrane. Although a hydrops usually causes increased scarring of the cornea, occasionally it will benefit a patient by creating a flatter cone, aiding the fitting of contact lenses. Corneal transplantation is not usually indicated during corneal hydrops.
Berthold Seitz is a German ophthalmologist, professor and director of the Department of Ophthalmology at the Saarland University Medical Center in Homburg, Saarland. He is known for his scientific contributions in the fields of cornea transplantation, cataract surgery and artificial lens-calculation after refractive corneal surgery as well as techniques of amniotic membrane transplantation and its histological integration patterns in the cornea.
Mahipal S. Sachdev is an Indian ophthalmologist and the Chairman of Centre for Sight, a chain of Eye Hospitals in India. He is known as one of the pioneers of Phacoemulsification procedure in India. He is the co-author of A Practical Guide to Phacoemulsification, the first Indian book on the topic. The Government of India awarded him the fourth highest civilian honour of the Padma Shri, in 2007, for his contributions to Indian medicine. He is the Chairman Scientific Committee of the Intraocular Implant and Refractive Society of India, IIRSI.
Allon Barsam is a London-based ophthalmologist specializing in cataract surgery, refractive surgery and corneal and external eye disease. Barsam carried out the first human treatments of microwave keratoplasty.
Atul Kumar is an Indian ophthalmologist who is currently the Chief & Professor of Ophthalmology at Dr. Rajendra Prasad Centre for Ophthalmic Sciences (RPC-AIIMS), the national apex ophthalmic centre at All India Institute of Medical Sciences, Delhi. He was awarded the Padma Shri award in January 2007 for his services to the medical field. He specializes in vitreoretinal surgery and also heads the Vitreo-Retinal, Uvea and ROP services at RPC-AIIMS.
Peripheral Ulcerative Keratitis (PUK) is a group of destructive inflammatory diseases involving the peripheral cornea in human eyes. The symptoms of PUK include pain, redness of the eyeball, photophobia, and decreased vision accompanied by distinctive signs of crescent-shaped damage of the cornea. The causes of this disease are broad, ranging from injuries, contamination of contact lenses, to association with other systemic conditions. PUK is associated with different ocular and systemic diseases. Mooren's ulcer is a common form of PUK. The majority of PUK is mediated by local or systemic immunological processes, which can lead to inflammation and eventually tissue damage. Standard PUK diagnostic test involves reviewing the medical history and a completing physical examinations. Two major treatments are the use of medications such as corticosteroids or other immunosuppressive agents and surgical resection of the conjunctiva. The prognosis of PUK is unclear with one study providing potential complications. PUK is a rare condition with an estimated incidence of 3 per million annually.
